About a month ago, Dropcam released Dropcam Pro ($199), an upgraded version of its previous camera, the Dropcam HD ($150). This new version boasts quite a few improvements over the HD version (which is now simply known as "Dropcam" and nothing more), like a wider field of view, increased zoom, improved low light vision (night vision), and better audio quality. So, basically everything. Well, everything that matters anyway. The real question is "how useful is it?" – it's not only useful, but versatile.
